Whistle is a small speech-to-text (speech recognition) model from Cactus. According to a creator review, the model file is about 16.9 MB and runs on CPU with no external dependencies, which makes it suited to on-device and edge use.
It processes audio in 30-second windows, detects the spoken language automatically and returns word-level timestamps. The same review reports a lower word error rate and faster decoding than OpenAI's Whisper Base. These figures come from a creator's summary, not from an official page, and have not been verified here.
No official page, repository or model card could be fetched, so the licence, pricing, release date and distribution channels are unconfirmed.
